Consider a signal x(n) with following factors:
1. x(n) is real and even signal
2. The period of x(n) is N = 10
3. x(11) = 5

Consider a discrete time signal x(n) = {-1, 2, -3, 2, -1} value of ∠x(eiω) is equal to
A low pass filter with impulse response h1(n) has spectrum H1 (eiω) shown below.
Here only one period has been shown by reversing every second sign of h1(n) a new filter having impulse response h2(t) is created. The spectrum of H2(eiω) is given by

1. x[n] = 0 for, n > 0
2. x [ 0] > 0
The signal x[n] is
A causal and stable LTI system has the property that,
The frequency response H(eiΩ) for this system is
